Service
It is possible to detect the sources of noises and vibrations more precisely via acceleration sensors and/or
microphones. Information such as engine speed and vehicle speed, which is required for subsequent analysis, is
recorded in addition to the noise recording via the OBD adapter VAS 6154.
Audi e-tron vehicles:
Ensure that the newest PICO software version is installed, otherwise a vehicle speed signal cannot be
recorded via the on-board diagnosis adapter.
In the PICO software, the setting “EV” must be selected when connecting the on-board diagnosis
adapter VAS 6154.
The attached guidelines answer many questions and can be used to provide support and practical instructions on
using the VAS 611 015 PICO NVH Tool.
The following is attached to this TSB (Figure 1):
• The Guidelines for acoustic analysis with the Pico NVH kit for noise analysis.
• The analysis guidelines for the measuring points on the transmission.
• Connecting VAS 6154 to PICO NVH tool VAS 611 015.
